Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, trim removal tools (if necessary).
Ensure the vehicle is parked safely and the ignition is off.
Disconnect the negative battery terminal to prevent any electrical shorts during repair.

2. Inspect and Replace Fuses

Locate the fuse box, typically located under the dashboard or in the engine compartment.
Identify the fuse related to the infotainment system (refer to the owner's manual for the exact fuse number).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reconnect the battery terminal and test the touchscreen.

3. Check Wiring Connections

Remove the dashboard trim if necessary to access the touchscreen connector.
Gently disconnect the wiring harness from the back of the touchscreen.
Inspect the connectors and wiring for any signs of damage or corrosion.
Clean the connectors with electrical contact cleaner and reconnect securely.
Reassemble the trim and test the touchscreen functionality.

4. Perform Software Update

With the vehicle in "Park," access the settings menu on the touchscreen (if operational).
Navigate to the software update section and check for available updates.
Follow on-screen instructions to download and install any updates.
If the screen remains unresponsive, this step may require a service center intervention.
